Scientific illustration combines both fields of art and science for the purpose of visually communicating scientific information. A medical illustrator is a professional artist with extensive training in medicine and science who creates visual material to help record and disseminate medical, biological and related knowledge. One of my favourite definitions of a medical illustrator is by- Bill Gramley, Neal Pointer, Bill Winn, 1978:

" Medical Illustrators draw what can't be seen, watch what's never been done, and tell thousands about it without saying a word "
